(Cl. 214 -38) ABSTRACT OF THE DISCLOSURE A trash collectingtruck has a trash tank removably carried on the truck chassis. A tailgate pivotally secured to the front end of the truck when in loweredposition can push trashthrough a door opening'in the rear end of thetank. When the tail is l'fted clear of the tank by a winch carried bythe truck, then the tank can be dragged off the truck onto anothercarrier such as a railroad fiat car.

This invention relates to a trash truck for collecting trash and, inparticular, to a trash truck having a removable trash receiving body ortank.

In the copending application of Roedel et a1., S.N. 497,312, filed Oct.18, 1965, for Trash Truck, a truck is disclosed in which the truck bodyor trash holding tank has an open rear end and a movable tail gate issecured to the truck chassis for loading trash into the tank andcompact'ng the trash and as a closure for the openng in the tank. Thistail gate can be swung out to open the tank by being pivotally securedto the chassis so that it is movable backwardly and downwardly, wherebytrash can be removed from the tank, or the tank can be vertically liftedand removed from the chassis.

The principal feature of such construction is in that, after the tailgate has been swung backwardly and downwardly, a conventional cranewit-h a suitable lifting beam can be used to remove a trash-filled tankfrom the truck and replace it with an empty tank.

The object of this invention is to produce a d fferent means forhandling a removable trash tank. In this invention, a movable tail gateis pivotally joined to the truck chassis adjacent the front end thereofin such a manner that it can be lowered or lifted so the tank can beremoved from the chassis. In this invention, the tank is mounted onwheels so that it can be rolled off the chassis by pulling it backwardsby means of a rope winch installed adjacent the front end of thechassis. A tow rope having a hook and running around a sheave is used topull the tank across a steel plate forming a bridge between the trashtruck and onto a different tank carrier, such as a railroad fiatcar.

A flat train can be formed of a plurality of these fiat- CZllS.Preferably, the length of the trash tank is not greater than the widthof the different tank carrier, such as a flatcar. A further feature ofthe invention is in that a hoistening rope can be attached to the ropewinch for lifting and lowering the tail gate for the tank.

The means by which the objects of the invention are obtained aredescribed more fully with reference to the accompanying schematicdrawing showing the front view of the trash truck.

Truck 1 has a chassis 1'. The tail gate 2 is pivotally secured by pivotpins 3 to the chassis 1. Tail gate 2 is adapted to be lifted from alower position as shown in dashed lines to the position shown in fulllines. This tail 3,380,660 Patented Apr. I 30, 1 968 gate is providedwith a hydraulically operated trash thrust member 12 and a trashcom-pressing plate 13 opthe vertical plane of pins 3 guides hoisteningrope and extends between tail gate 2 and winch 6 which is carried bychassis 1. Thus hoistening rope 5 can either lift or lower tail gate 2.Trash tank 7 is mounted on wheels 8 so that it can be easily and quicklymoved. Trash tank 7 has a rear door opening 7a which is closable by atop cover 16, a center cover 17 which partially closes the opening, anda lower cover 18 which can be moved to close the door openingcompletely. Top cover 16 is movably attached to tank 7, center cover 17is movably connected to cover 16, and lower cover 18 is hinged to cover17. A tow rope 6 which is attached to winch 6 is adapted to be extendedacross a different tank carrier such as flatcar 9 and around a sheave 10and ending in a hook 6-". When tail gate 2 has been lifted, hook 6 isattached to tank 7 and the winch operated so that tank 7 can be pulledoff of the chassis 1' across a temporary metal bridge plate 11 and ontoflatcar 9. As shown in the drawing, the length of tank 7 isapproximately the same as the width of flatcar 9 with due regard fortransportation safety.

The trash truck 7, as provided in this invention, wIth the tail gate 2and the tank 7 easily movable on rollers or wheels 8 so that it can beplaced on a different carrier means that communities composed of smallcities or farm areas can be serviced by one trash truck because of thequickness with which a filled trash tank can be removed and placed on adifferent carrier for further transport to a large tr-ash collectingarea.

Having now described the means by which the objects of the invention areobtained, we claim:

1. A trash collecting truck comprising a chassis, a drivers cab on saidchassis, a trash tank remova-bly carried on the chassis, a door openingin the rear end of said tank, a tail gate pivotally secured to the frontend of said chassis, drive means secured to said chassis and said tailgate for pivotally moving said gate, and trash thrust means carried bysaid tail gate for moving trash deposited on said tail gate into saidtank, and lifting means for swinging said tail gate upwardly and clearof said tank so that said tank is liftable rearwardly from said chassis.

2. A truck as in claim 1, further comprising wheel means movablysupporting said tank, and winch means including a tow rope and a hookmounted on said chassis for pulling said tank off said chassis across abridge plate and onto a different tank carrier.

3. A truck as in claim 2, said tank having a length approximately notgreater than the width of said different tank carrier.

4. A truck as in claim 2, said means for swinging said tail gateupwardly further comprising a sheave mounted on said chassis, and ahoistening rope running over said sheave and connecting said winch meansand said tail gate.
